Patent EP-0715657-A1 (EP)
Inventor: TORGET ROBERT W
IPC: C08H8/00
Filed: 1994-09-23
Abstract: The invention relates to the prehydrolysis of lignocellulose by passing an acidic or alkaline solution through solid lignocellulosic particles with removal of soluble components as they are formed. The technique permits a less severe combination of pH, temperature and time than conventional prehydrolysis. Furthermore, greater extraction of both hemicellulose and lignin occurs simultaneously in the same reactor and under the same conditions.

Filed: 1994-10-12
Abstract: Dispositif d'étanchéité pour obturateur à coulisse se plaçant en travers du canal d'extrusion d'un appareil de filtrage de polymères. Ledit dispositif comporte un joint annulaire dont la surface d'étanchéité est plaquée sur la plaque de l'obturateur par un ressort annulaire. Ledit joint présente une surface de pression oblique par rapport à sa surface d'étanchéité et située à une extrémité axiale du joint opposée à la surface d'étanchéité. Le ressort annulaire exerce sur la surface d'étanchéité des forces radiales qui ont pour effet de plaquer le joint axialement sur l'obturateur. La pression du polymère régnant dans le canal d'extrusion s'ajoute aux forces plaquant le joint sur l'obturateur.

Abstract: L'invention concerne des pigments organiques chargés, leur procédé de production ainsi que leur utilisation dans des formulations de peinture, notamment des formulations appropriées à la signalisation routière. Les pigments de l'invention comprennent typiquement une âme de lithopone particulaire enrobée d'une couche d'un pigment organique. Selon les modes de réalisation préférés, le pigment comprend un composé azoïque, les pigments sont enduits de colophane, et/ou l'âme contient également un colorant ou une matière dopante, typiquement un oxyde ou un sel métallique. Un procédé cité à titre d'exemple consiste à mélanger un lithopone particulaire avec un copulant tel qu'une acétoacet-o-anisidide. On ajoute ensuite un agent de précipitation du copulant, typiquement un acidifiant, en une quantité suffisante pour précipiter le copulant sur le lithopone. On fait ensuite réagir le copulant lié au lithopone avec un ion diazonium dans une réaction de couplage azoïque afin de former un pigment. On peut ensuite chauffer et enrober les particules de lithopone enrobées de pigments d'une colophane ou d'un savon de colophane modifié.
